Demand for VAT: Recovering a debt to the Crown: Unauthorised issuer procedures

That is, an unauthorised person has charged a sum on that invoice as VAT that is not VAT chargeable. VAEC9660 provides legal and practical definitions of unauthorised person
Recovery of sums charged incorrectly as VAT on an invoice must be made by means of a formal demand as the form VAT 641 Notice of Assessment cannot be used for this purpose.
